A mall in Chongqing has introduced an exclusive restroom for its elite shoppers. According to the Telegraph, shoppers spending 5000RMB can have access to the toilet. The article doesn't mention if this is a one-time deal or if shoppers have to spend 5000RMB each time to relieve themselves in the harmonious toilet. There's also no word on whether or not it's a squatter.
